T0 all whoma't may concern.

Be it known that I, GLnNDoN A. RICH- Anus, a citizen of the UnitedStates of America, residing at Grand Rapids, in thev county of Kent andState of Michigan, have invented certain new and useful Improvements inSupporting and Alining Devices for Casings for Steam-Pipes; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in supporting and' alining devicesfor casings for steam pipes and more particularly to such devices usedin connection with casings which are to be laid under ground or in otherplaces exposed to moisture and its object is to provide the same withsuitable drainage to carry away any water that may accumulate near thesame; to provide a suitable support to maintain the casing in alinementand to provide the same with various new and useful features hereinaftermore fully described and particularly pointed out in the claim referencebeing had to the accompanying drawings in which Figure l is a sideelevation of a device embodying my invention having a pipe covering or'casing mounted thereon; Fig. 2 a longitudinal vertical section of thesame; and Fig. 3 a transverse section of the same on the line 3--3 ofFig. l.

To convey away any water that may accumulate about the casing bycondensation or seepage, and to support the casing in alinement, Iprovide a chair 3 having a broad base, inwardly sloping sides and aconcave upper surface in which the pipe casing 1 is supported andalined. This chair is strengthened by a middle rib 3a dividing theinterior into tile like conducting passages through which anyaccumulated water may escape. These chairs are made in sections, eachsection having the same length as a section of the casing 1, and atransverse concave recess 4 is provided in the center of the same toreceive the enlarged connecting flange of the casing 1. These chairs arepreferably made ofun glazed or porous material which will permitmoisture to penetrate them and be conveyed away through the passages inthe body of the chairs. It will be observed that there is a greatadvantage in arranging the lengths of the casing 1, and the chairs 3, sothat the joints of the casing are firmly supported from each end by thatportion of the chair whichv extends each side from the depression 4, andlikewise the load is balanced upon each chair in such a way that therewill be no sa-g in the casing 1 to break or' open up the joints. Thejoints of the casing and of the chairs are staggered, thus malntaining aperfect alinement and level of the casing 1, and at the same time a tileis provided which will convey away any water or moisture that mayaccumulate.

The combination with a plurality of connected up casings havingcircumferentially enlarged connecting flanges, of a plurality of hollowsupporting members disposed below said pipe casings end to end withtheir hollow portions in alinement, said hollow members having concavedupper sides for receiving said pipe sections, said members havinghorizontal bases and slanting side walls extending upwardly to saidconcave portions, each of said sections having transversely extendingrecesses for receiving the connecting flanges of the pipe casings, saidrecesses being greater in width than the width of the connecting flangesor permitting of a slight longitudinal movement of the pipe casings, andsaid recesses having their bottoms disposed parallel to the bases of thesupporting members and the ends of said recesses opening through thesides of the supporting members whereby any foreign object entering saidrecesses can be readily removed therefrom, and a longitudinallyextending connecting web disposed in each of said supporting members.

In testimony whereof I alix my signature in presence of two witnesses.
